Stephen Ambrose

Popular historian and biographer Stephen Ambrose – perhaps best known for his 1992 book "Band of Brothers" – was embroiled in a plagiarism scandal in 2002 when charges were made that he had taken sections of historian Thomas Childers' book "Wings of Morning" and put them in his book "The Wild Blue." Ambrose apologized, then an investigation by Forbes.com revealed that passages in some of his other books, including "Crazy Horse and Custer," were similar to sections of books by other authors.
